PowerBook Motion Sensor

How can I add this sensor to my old 1.33 Ghz 17" PowerBook to park its HardDisk?
I have used a program called amstracker and AMSVisualizer on a Motion Sensor equipped machine and these hacks work as described. Now I would like to use them on an older PowerBook with the Sensor Hardware mod.
What type of hardware is it?
What are the specs?
And where do I get one?
Can something be built for the PCMCIA slot?

Uhhhhh..

I've not looked at the service manual yet, but I was under the impression that it is built into the drive.

Downloading now will let you know.

I was wrong...

It's built onto the logic board. Doesn't say who makes it...

Use that, a serial to usb chip, and a kext. That should work.

Wakeup call for me. Were have I been all those years.

There is an enormous amount of info on the web about Motion Sensor technology.
I was never aware of all the possibilities.
Thanks Amit Sihgh (NOT APPLE COMPUTER) for this eye opening wakeup call.
Here's some stuff for all of us newbies to checkout.

Google search for: 1. motion sensor OS X
2. accelerometer xyz
3. MEMS sensor (Micro Electro-Mechanical Systems)
